PURPOSE: To evaluate the potential advantages and disadvantages, success rate, and complications of this new procedure for glaucoma surgery, which includes the formation of a filtration fistula without any dissection of Tenon's capsule, as an alternative to trabeculectomy with or without pharmacological wound modulation. METHODS: Small incision trabeculectomy, avoiding Tenon's capsule, was performed in 40 glaucomatous eyes through a 2.5-mm limbal incision, and intraocular pressure (IOP) was monitored serially over a 12-month period. RESULTS: The mean postoperative IOP (16.60 ± 5.93 mmHg) at the 12-month follow-up was significantly lower than the mean preoperative IOP (30.20 ± 10.70 mmHg). Thirty-six eyes (90%) had an IOP of less than 22 mmHg without antiglaucomatous medications at the end of the 12-month follow-up. Blebs were pale and diffusely elevated. No serious complications were encountered. CONCLUSIONS: This new technique is a low-cost and safe alternative to conventional trabeculectomy, which effectively reduces IOP. The use of a small 2.5-mm incision, which obviates the dissection of Tenon's capsule and subsequent subconjunctival fibrosis, the absence of the need of any sophisticated instruments, and the absence of any of the major complications that are encountered with the use of antimetabolites, mean that this procedure can be performed more often in glaucomatous eyes needing filtration surgery.
